论文摘要
在微米尺度上量化温度变化可以为光学传感提供新的机会。在本文中，我们提出了一种新的方法，该方法是使用稀土掺杂的校玻璃荧光中温度依赖性变化的方法，以在200微米视野中提供温度变化的微米尺度图像。我们通过监测水滴的蒸发来证明系统，并报告净温度变化为7.04 K，灵敏度至少为0.12K。这些结果确定了这种基于共凝聚方法的实用性，以提供高分辨率标记的无分辨率光学温度感应。
Quantifying temperature variations at the micron scale can provide new opportunities in optical sensing. In this paper, we present a novel approach using the temperature-dependent variations in fluorescence of rare-earth doped tellurite glass to provide a micron-scale image of temperature variations over a 200 micrometre field of view. We demonstrate the system by monitoring the evaporation of a water droplet and report a net temperature change of 7.04 K with a sensitivity of at least 0.12 K. These results establish the practicality of this confocal-based approach to provide high-resolution marker-free optical temperature sensing.
